Android Saripaar is a simple, yet powerful rule-based UI validation library for Android. It following features declarative style validation powered by Annotations, synchronous and asynchronous validations (you don't have to worry about threading), compatibility with Stock Android Widgets, custom view dependencies, quick setup (just download the jar and include it in your libs project folder), removal of most of your validation logic from your code, and compatibility with other annotation frameworks such as AndroidAnnotations, RoboGuice, etc.,

Unlike other Java to Objective-C solutions, Java-Objective-C Bridge doesn't require any code generation of class stubs. It allows you to use any Objective-C libraries and frameworks from Java without having to write any native code. In addition to being able to use Objective-C objects, it allows you to pass Java objects to the objective-c runtime as delegates, so that you can write an entire Cocoa application in Java.
The bridge provides 3 levels of abstraction. At the lowest level, it provides wrappers around the Objective-C runtime functions. At a slightly higher level of abstraction, it provides a procedural API to send messages to the Objective-C runtime. At the highest level of abstraction, it provides a Proxy class that serves as a wrapper around any Objective-C object that allows you to work with it in Java almost the same as if you were in Objective-C.

log4javascript provides JavaScript developers with
a familiar, robust, and flexible logging framework
with which to debug JavaScript applications. This
is becoming increasingly important as Web
interfaces become richer. log4javascript is based
on Java's log4j and is tested and works across all
recent major browsers, including IE5+ (for
Windows), Firefox, Mozilla, Netscape 7+, Safari
1.3+, Opera 7.5+, Konqueror 3.4+, and Google Chrome.

DSFoundation is a foundation enhancement library for Objective-C. It includes an IOC (Inversion of Control) container, translation (serialization and conversion) to and from Objects, YAML, and XML, automatic KVC adaptation and compliance, logging through an integrated Log4Cocoa, regular expression extensions, and much more.

retrobi creates Web publications of library bibliographies. The biggest collection using it has more than two million items. A Windows application can be used for collecting, describing, and uploading scanned items.

iLib is an internationalization library for JavaScript that was created because with the advent of AJAX, it is no longer possible to avoid internationalization. Previously, you could format dates in the user's locale on the server. Now, Web services called via AJAX return time stamps in Unix time and formatting has to be done in the browser, but the standard library is inadequate. In addition to dates, the library handles times, numbers, currency, percentages, calendar calculations (Arabic, Hebrew, Gregorian, and Julian), time zones, string translation, string formatting and choice formats, locale info, ctype functions, and Unicode normalization.

Pocket Bandit is a slot machine game for Android. It features a retro style with three reels and ten stops, and is modelled after the classic, mechanical fruit machines of the early 20th century and emulates devices such as the Mills Novelty QT Chevron, Mills Novelty Vestpocket, Groetchen IMP trade simulator, Pace Comet, and Liberty Bell. Unlike the original machines, it also includes
elements of skilled and strategic play. You can spin the reels at different speeds by pulling the knob at different speeds, stop a reel at will by yanking the knob up, wager zero to three coins per round, and use no-wager rounds to skip over bad luck streaks.

The !CHAOS project is aiming at the development of a new concept of a control system and data acquisition framework providing, with a high level of abstraction, all the services needed for controlling and managing a large scientific or non-scientific infrastructure.
